Power Supply for Nano

sasquatch84

So I am planning on using the Arduino nano for the brains of my garden watering project.  I have a 12 volt power converter I kept from an old set of boot dryers that fell apart years ago.  I know that the Nano can handle the volts but seeing as it's at the higher end of the acceptable range and I want to leave this thing plugged in 24/7, I think I'll use one of my 7805's.  And since they lower voltage to 5 volts, I assume I can just run the power straight into the 5v pin. 

Does this seem like a waste of time?

Also, am I blogging properly?  I am so green...:(

    You should be ok as it has been designed to work with 12v supplies.

     

    It will also depend on what else you are planning on powering through the Nano's voltage regulator. Sounds like your project may be driving solenoids etc. which you will want to look at powering separately from the Nano's supply.

     

    If you power it up you will soon find out how much it heats up.
